Always liked AMSOIL ever since I first started using it racing motocross. Now run it in all my equipment. Switching my tractor to it next.

I used this hydraulic oil for my 50 hour service on my Kioti CK 4020. Amazing! The hydraulic controls work much smoother and the whole machine is much quieter! Highly recommend!

Best you can buy. Can't beat it. I use Amsoil in all 4 vehicles and always will.

I was introduced to Amsoil and there products and glad so far I made the switch from Mobile. Will see how it it goes when I pull the 5th wheel RV next week.

Oil field, off road, 129,000 lbs, and on road grades up to 8%, off road grades up to 16%, pulling a super set of 108’ in combination length. The truck is a 2019 Peterbilt 389 with a 565 x15 Cummins, 18spd manual, 3:90 rear ends and lockers inside 23,000 lb housings. To date, the engine oil has been replaced with the 15w40 signature series as well as the Amsoil bypass system. The engine coolant has also been replaced with the Amsoil 1,000,000 mile coolant and the differential fluids have also been changed to the Amsoil Severe gear 100% synthetic 75w140. Under these extreme conditions, these Amsoil products are providing exceptional performance and durability. My truck is not building heat from friction caused by wear. The other drivers I work with are already complaining about their trucks building heat from the coolant temperatures to engine oil temperatures to differential temperatures. I have no such complaints. These products are truly the BEST in synthetics. Thanks Amsoil for keeping my truck on and off road and out of the shops

Winter time mixing with other AMS oils. Working very good.

I like the data backed science behind the amsoil products. I have had my amsoil analyzed by independent third party companies after various mileage intervals (5k, 10k and 20k+) and the oil still had good lubrication characteristics (tbn) at even 20k+ miles.

Can’t beat this stuff I run it in my F350

Smooth and easy Send my promotional product. That I asked for 3 times... Let's see if I get a response.

Good oil buy it

Much better starting in the morning on cold winter days. I don’t drive it very often now so I change the oil only once a year with this oil. That’s less than 5000 miles.

Been running in my 05’ 6.0 powerstroke and have great results

No issues for 20 years. I have used this product and will Continue to

I have been using Amsoil now for 2yrs straight. I started using this motor oil with my F350 dually, and also use the Amsoil 20micron filter. So far so good. I have seen the oil retain its viscosity better during my regular oil change frequency as compared to the Rotella T I was using (NOTE: Rotella T is great oil also). As a result, I have become an Amsoil convert. Am still sticking to the traditional Ford oil change frequency that is estimated by the truck's onboard computer (approx 7000mi), for the simple reason that oil is relatively cheap when compared to the price of a failed engine. :-) Last, from the information I have read I do think that Amsoil will extend the life of my engine (currently at approximately 160,000mi).

Lightning fast shipping! Great motor oil. Says you can use it for extended mileage, altho when I change my oil I can feel and hear the Motor running quieter and it feels smoother. Maybe thats a filter thing but I don't push it that far past OM recommendations. I bout my 2018 Ram with the Cummins in 2019 with 420 miles on it and this is the only oil I have used! Got 170k on it now. It's completely stock. I use the Stratapore filter by fleetguard.

I have been using Amsoil Diesel oil since I started farming and bought my first tractor, a used JD 4430 in 1979. That tractor is still used in my farming operation. It still does not use any oil, starts better in cold weather, and has been less expensive to maintain by far than neighbors using even other brands of synthetic oils.

Great oil, been using from day one ever since I bought my truck brand new!

I only run Amsoil Signature Series in my Twin-Turbo BMW X5s. I run them pretty hard and keep them serviced every 6000 miles and NO problems ever-Thanks! Jim

Good product

I've been a diesel tech, boat tech and advisor for years now. I started using AMSOIL in my 00 7.3l a long time ago, I noticed smoother injector operation and better response. Since then, AMSOIL is in all of my diesels! My 19 model SuperDuty feels more free and helps with response and keeping decent mileage. I use the filters as well! I will continue using AMSOIL over typical conventional oils, thanks AMSOIL for a great product.
